Description

Technical Field

[0001] This utility model relates to the technical field of kayaks, and in particular to the technical field of kayak steering structures. Background Technology

[0002] Kayaking is a common water sport in which participants compete in calm or rapid waters. Kayaks are also often used for recreational and adventure activities, allowing people to paddle in natural waters and enjoy the beauty of nature.

[0003] However, most existing kayaks are made of composite materials and are molded in one piece. They have a long and narrow structure and need to be moved around during daily use. Because the kayaks are too long and narrow, the middle of the kayak will shake a lot when two people are carrying it. The composite materials are also relatively brittle and sometimes break the kayak, causing a lot of inconvenience to people's daily use.

[0004] To address the problems mentioned above, for example, application number CN201020272425.5 discloses a recreational kayak, comprising a symmetrical, elongated hull with a cabin on the hull. The hull has a rope-tying structure, including a lifting rope at one end of the hull. The free end of the lifting rope passes through a pressure plate and is fixed to a handle. The other end of the lifting rope is wrapped around the outer end of a lifting plate, and a main rope is wrapped around the inner end of the lifting plate. The main rope is also wrapped around a first hinge point, a second hinge point, a third hinge point, a fourth hinge point, a fifth hinge point, and a sixth hinge point on the edge of the hull. The sixth, seventh, eighth, ninth, and tenth hinge points, along with the third, fourth, fifth, eighth, ninth, and tenth hinge points and the first, second, sixth, and seventh hinge points, are located on the left and right sides of the cabin. A rope structure is provided on the narrow hull. When the handle is pulled, the tension of the rope distributes the force on the narrow hull to the lifting plate, and the main rope and other ropes are also tensioned. This greatly reduces the vertical vibration of the middle of the kayak during transportation, which helps to protect the narrow hull.

[0005] However, the kayak in the aforementioned patent does not have a protective structure. When used for rescue or daily life, if the water flow is strong, the kayak may collide with rocks or other sharp objects, which may cause damage to the kayak and lead to air leakage.

[0006] To address the problems mentioned above, for example, application number CN201720255453.8 discloses a multi-purpose lifeboat. The lifeboat includes a hull for riding, a connecting component for handrails on the hull, and a protective component for reinforcement on the side of the hull. The connecting component includes a connecting strap on the hull and a loop on the hull for attaching to the wrist. The protective component includes a protective plate adapted to the outer side of the hull to increase strength and a Velcro fastener connected to the protective plate. By adding the protective component to the side of the lifeboat, the strength of the lifeboat is increased, preventing surface damage when the lifeboat is subjected to external impact and extending the lifespan of the lifeboat.

[0007] However, the aforementioned patents still have the following drawbacks:

[0008] The kayak described in the aforementioned patent lacks a steering mechanism, requiring the user to use both hands to swing the oars to control the kayak's direction, thus preventing them from focusing on paddling or other operations, thereby reducing the convenience and safety of kayak operation. Summary of the Invention

[0009] The purpose of this invention is to solve the problems in the prior art by proposing a kayak steering structure that can convert the user's foot movements into precise deflection of the rudder, thereby freeing the user's hands so that they can focus on paddling or other operations.

[0010] To achieve the above objectives, this utility model proposes a kayak steering structure, including a kayak body, a front cabin, a rear cabin, a fixed plate, a rotating disk, a first fixed block, a second fixed block, a steering stick, an arc-shaped guide groove, a steering rope, a steering frame, and a rudder blade. The front and rear ends of the kayak body are respectively provided with a front cabin and a rear cabin, and the two inward-facing sides of the kayak body are respectively provided with openings communicating with the front cabin and the rear cabin. A fixed plate is provided in the front cabin, and a rotating disk is provided on the fixed plate. A first fixed block and a second fixed block are provided on the rotating disk, and a steering stick is provided between the first fixed block and the second fixed block. The rear end of the steering stick extends from the opening in the front cabin. An arc-shaped guide groove is provided on the outer circumferential edge of the rotating disk, and the steering rope is slidably accommodated in the arc-shaped guide groove. A steering frame is provided in the rear cabin, and the end of the steering rope is fixedly connected to the steering frame. A rudder blade is connected below the steering frame.

[0011] Preferably, a seating compartment is provided in the upper middle part of the kayak body.

[0012] Preferably, the rotating disk is rotatably connected to the fixed plate by a rotating bolt, so that the rotating disk rotates relative to the fixed plate around the rotating bolt, and the end of the rotating bolt is equipped with a nut.

[0013] Preferably, the first fixing block is fixedly connected to the rotating disk by a first fixing screw.

[0014] Preferably, the second fixing block is fixedly connected to the first fixing block by a second fixing screw.

[0015] Preferably, the first fixing block and the second fixing block each have a semi-circular groove on their sides that are close to each other. The two semi-circular grooves together form a circle, and the front end of the steering stick is located within the circle formed by the two semi-circular grooves.

[0016] The beneficial effects of this utility model are:

[0017] 1. This utility model, through the combined action of a rotating disc, a first fixed block, a second fixed block, a steering stick, an arc-shaped guide groove, a steering rope, a steering frame, and a rudder blade, can improve the convenience and safety of kayak control. When the user controls the steering stick with both feet to make left and right swinging movements, the swinging movement of the steering stick directly drives the rotating disc connected to it to rotate around its rotating bolt. When the rotating disc rotates, its arc-shaped guide groove exerts a traction effect on the steering rope, causing the steering rope to undergo relative displacement within the arc-shaped guide groove. The traction movement of the steering rope is transmitted to the steering frame, which in turn drives the steering frame and the rudder blade below it to swing left and right around the rudder shaft. This frees the user's hands, allowing them to focus on paddling or other operations, greatly improving the convenience and safety of kayak control, and is especially suitable for water scenarios where multiple operations need to be performed simultaneously.

[0018] 2. By setting an arc-shaped guide groove, this utility model provides a continuous, smooth, and constrained movement path for the steering rope, thereby ensuring that the steering rope always moves in close contact with the guide groove during traction, effectively preventing the steering rope from derailing, slipping, or becoming unnecessarily entangled, thus enhancing the stability and durability of the device.

Detailed Implementation

[0024] See Figures 1 to 4 This utility model relates to a kayak steering structure, comprising a kayak body 1, a front cabin 2, a rear cabin 3, a fixed plate 4, a rotating disk 5, a first fixed block 6, a second fixed block 7, a steering stick 8, an arc-shaped guide groove 9, a steering rope 10, a steering frame 11, and a rudder blade 12. The front and rear ends of the kayak body 1 are respectively provided with a front cabin 2 and a rear cabin 3. Openings communicating with the front cabin 2 and the rear cabin 3 are respectively opened on the inward-facing sides of the kayak body 1. A fixed plate 4 is provided inside the front cabin 2, and a rotating disk 5 is provided on the fixed plate 4. The rotating disk 5 is provided with a first fixing block 6 and a second fixing block 7. A steering stick 8 is provided between the first fixing block 6 and the second fixing block 7. The rear end of the steering stick 8 extends out from the opening of the front compartment 2. An arc-shaped guide groove 9 is provided on the outer circumferential edge of the rotating disk 5. The steering rope 10 is wrapped around and slidably accommodated in the arc-shaped guide groove 9. A steering frame 11 is provided in the rear compartment 3. The end of the steering rope 10 is fixedly connected to the steering frame 11. A rudder blade 12 is connected below the steering frame 11.

[0025] When the user controls the steering stick 8 with both feet to swing it left and right, the swinging motion of the steering stick 8 directly drives the rotating disk 5 connected to it to rotate around its rotating bolt 14. When the rotating disk 5 rotates, its arc-shaped guide groove 9 exerts a pulling effect on the steering rope 10, causing the steering rope 10 to undergo relative displacement within the arc-shaped guide groove 9. The pulling motion of the steering rope 10 is transmitted to the steering frame 11, which in turn drives the steering frame 11 and the rudder blade 12 below it to swing left and right around the rudder shaft.

[0026] See Figure 1 The kayak body 1 has a seat cabin 13 located in the middle of its upper part. The seat cabin 13 allows the user to control the movement of the kayak body 1 while sitting inside it.

[0027] See Figure 4 The rotating disk 5 is rotatably connected to the fixed plate 4 via a rotating bolt 14, so that the rotating disk 5 rotates relative to the fixed plate 4 around the rotating bolt 14. The end of the rotating bolt 14 is equipped with a nut 15. By setting the rotating bolt 14, the rotating disk 5 can rotate relative to the fixed plate 4 around the rotating bolt 14, thereby driving the steering rope 10 to generate a traction effect.

[0028] See Figure 4 The first fixing block 6 is fixedly connected to the rotating disk 5 by the first fixing screw 16. By setting the first fixing screw 16, the first fixing block 6 and the rotating disk 5 are tightly connected, ensuring the overall stability of the device.

[0029] See Figure 4 The second fixing block 7 is fixedly connected to the first fixing block 6 by the second fixing screw 17. By setting the second fixing screw 17, the second fixing block 7 and the first fixing block 6 are tightly connected, thereby ensuring the stable operation of the steering stick 8.

[0030] See Figure 4 The first fixing block 6 and the second fixing block 7 each have a semi-circular groove 18 on their sides that are close to each other. The two semi-circular grooves 18 together form a circle, and the front end of the steering stick 8 is located inside the circle formed by the two semi-circular grooves 18. This allows the steering stick 8 to directly drive the rotating disk 5 to rotate when it moves, thereby driving the steering rope 10 to generate traction and causing the rudder blade 12 to swing in direction.

[0031] The working process of this utility model:

[0032] In operation, when the user controls the steering stick 8 with both feet to swing it left and right, the swinging motion of the steering stick 8 directly drives the rotating disk 5 connected to it to rotate around its rotating bolt 14. When the rotating disk 5 rotates, its arc-shaped guide groove 9 exerts a pulling effect on the steering rope 10, causing the steering rope 10 to undergo relative displacement within the arc-shaped guide groove 9. The pulling motion of the steering rope 10 is transmitted to the steering frame 11, which in turn drives the steering frame 11 and the rudder blade 12 below it to swing left and right around the rudder shaft. This frees the user's hands, allowing them to focus on paddling or other operations, greatly improving the convenience and safety of kayak control, and is especially suitable for water scenarios where multiple operations need to be performed simultaneously.

[0033] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
